EDL not working (closes connection after couple seconds)

[Eli97]

Hi there, I tried to flash HyperOS to my Redmi Note 12 pro 5G, but after flashing I got a hard brick, no screen, nothing, only the sounds on Windows telling me it is connected. But when I try to connect in Windows, it recognizes the com port, but after a couple seconds it disables the connection. That way I might never be able to flash new firmware through EDL. Someone a tip to make the connection stable in EDL?
